Waste collection systems

Abstract

Apparatus for the removal of waste material from a manufacturing operation comprising a box into which the waste material is fed, lid means for the box movable between open and closed positions and means for establishing a current of conveying air through said box when said lid means is closed.

What is claimed is: 
     
       1. Apparatus for the removal of waste material produced from a manufacturing operation comprising a box into which the waste material may be fed, said box having a top opening through which said waste material may be introduced, lid means for the box mounted to be movable between a box-open position wherein it uncovers said opening and a box-closed position wherein it closes said opening, means whereby said lid means in box-closed position accummulates waste material and whereby said accummulated waste material is introduced through said opening into said box when said lid means is moved from box-closed to box-open position, and means for establishing a current of conveying air through said box when said lid means is in said box-closed position. 
     
     
       2. Apparatus according to claim 1 wherein separate ducts connect opposed open ends of the box to positions outside of the space in which said manufacturing operation is housed. 
     
     
       3. Apparatus according to claim 1 wherein said lid means is constructed and arranged to receive waste material on its upper surface when in box-closed position and to deposit such waste material directly in the box when moved to its box-open position. 
     
     
       4. Apparatus according to claim 2 wherein valve means is included in one of said ducts, which valve means is adpated to be opened to establish said current of conveying air whenever said lid means is in box-closed position. 
     
     
       5. In the apparatus defined in claim 1, deflector means adjacent said box constructed and arranged to direct waste material onto the upper surface of said lid means when the lid means is in box-closed position. 
     
     
       6. In the apparatus defined in claim 5, said deflector means being a baffle plate fixed on and extending above said box. 
     
     
       7. In the apparatus defined in claim 5, said air conveying means including means defining a chamber alongside said box, said chamber having a top wall provided with apertures that are constructed and arranged to direct waste material toward said deflector means in the box-closed position of said lid means.
